Rob was noticeably absent from the wedding in Florence, Italy, but Kim still calls Rob her "best friend." She told host Andy Cohen, "My brother and I are so close. He’s one of my best friends.
"I’m definitely a tough love kind of person. If I don’t like something that’s going on in my life, I change it, and I don’t’ sit and complain about it for a year... I try to encourage him. And once you don’t make that change for so long, and it’s not happening, I get frustrated. My patience runs out."
As for the details on how she learned Rob would not be attending her wedding, she said, "He sent me a long email the morning of that he was going to leave and there was no fight. I just thought, you know what, this is my day, I’m not even going to worry about it, I hope he’s okay..."
"You can only pray and wish that someone would not miss out on more memories in life, because life is about memories. So, fix the problem. That’s just how I am."
After talking about her family, Kim helped Andy take the perfect selfie - and she would know, because she's writing a book on it. Check it out above.
